Answer
Attempt 1 out of 2
2, colon, 62:6
18, colon, 618:6
3, colon, 13:1
6, colon, 186:18
3, colon, 93:9

Answer 1

Equivalent ratios are those with each part multiplied by the same factor. For 1:31:3:

- 2:62:6 = 2*(1:31:3) (k=2) — equivalent
- 6:186:18 = 6*(1:31:3) (k=6) — equivalent
- 3:93:9 = 3*(1:31:3) (k=3) — equivalent

18:618:6 and 3:13:1 are not equivalent.
